Description

CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the priority of provisional patent application US No. 61/925940, filed January 10, 2014, the description of which is fully incorporated into this application by reference.

BACKGROUND OF THE INVENTION

Technical field

[0002] This invention generally relates to the field of connectors for a disposable disposable kit, and more specifically, to connectors of a disposable disposable kit configured to supply fluid to a patient.

Description of the Related Art

[0003] In many medical diagnostic and therapeutic procedures, a medical professional, such as a doctor, administers one or more medical fluids to a patient. In recent years, a number of medical fluid delivery systems have been developed for injecting fluids under pressure, for example, a contrast solution (which is often referred to simply as a “contrast agent”), a flushing agent such as saline, and other medical fluids for use in such procedures. such as angiography, computed tomography (CT), ultrasound diagnostics, magnetic resonance imaging (MRI), positron emission tomography (PET) and other molecular diagnostic procedures. In general, these medical fluid supply systems are designed to deliver a given amount of fluid at a given flow rate.

[0004] In some injection procedures, a healthcare provider inserts a catheter or needle into a patient's vein or artery. A catheter or needle is connected to either a manual or automatic fluid injection system through tubes and a connector that interacts with the fluid injection system. Automatic fluid injection systems typically comprise at least one syringe connected to at least one fluid injector comprising, for example, a mechanized linear piston. At least one syringe contains, for example, a source of contrast medium and / or a source of flushing fluid. The medical professional enters the settings into the electronic control system of the injector for the liquid in order to fix the volume of the contrast medium and / or saline solution and to fix the rate of administration for each of them. The disposable disposable kit connector and associated tubes are connected to a fluid delivery system to deliver one or more fluids to a patient.

[0005] Although various manual and automatic fluid delivery systems are known in the medical field, improved multi-fluid delivery systems are still required for use in medical diagnostic and therapeutic procedures in which one or more fluids are delivered to a patient. In addition, in the medical field, improved disposable disposable kit connectors are also needed that can be used with a multi-fluid delivery system to improve the delivery of one or more fluids to a patient. In the medical field, there is still a need for improved medical devices and systems used to deliver fluids to patients during various medical procedures.

SUMMARY OF THE INVENTION

The elastic protrusion may have a clamping surface which, when pressed, deflects the elastic protrusion from the engaged position into the free position. In some embodiments, the fluid inlet may include a housing surrounding at least a portion of the fluid inlet. The casing may have at least one recess to facilitate handling of the medical connector. The casing may have one or more ribs protruding beyond the outer surface of the casing. The fluid inlet may have a shape to prevent connection to the MUDS kit drain inlet, and the drain outlet is shaped to prevent being connected to the MUDS kit connector. The medical connector can be asymmetric so that the medical connector can be connected to the MUDS kit in only one orientation. At least one tide may be provided to prevent the medical connector from being improperly connected to the MUDS kit. In some embodiments, the second end of the fluid supply line to the patient may have a connector configured to releasably engage with the outlet for drainage while maintaining the sterility of the second end. The connector may be in fluid communication with a drain outlet. The connector may be a Luer connector. The non-return valve may be configured to maintain unidirectional flow through the fluid inlet socket to the patient fluid supply line. In some embodiments, at least one sensor element may be configured to interact with at least one sensor configured to detect the presence or absence of at least one sensor element indicating that the medical connector has been correctly inserted or installed. At least one sensor element comprises one or more reflective surfaces for reflecting visible or infrared light to at least one sensor. The fluid inlet includes at least one seal to seal the fluid inlet.

[0009] According to another embodiment, a disposable disposable kit connector may have a fluid inlet receptacle configured to releasably engage the MUDS kit connector for fluid communication therewith, and a drain outlet receptacle configured to demountably engage the input receptacle to drain the MUDS kit for installing a fluid connection with it. A splitter may be provided to separate the fluid inlet from the fluid outlet. The locking mechanism may be configured to be removably attached to the MUDS kit. The locking mechanism may have an elastic protrusion, which is configured to deviate from the engagement position to the free position and vice versa by deflecting at least part of the elastic protrusion. A patient fluid supply line may be connected at the first end to a fluid inlet socket. The connector may be connected to the second end of the fluid supply line to the patient. The fluid flow along the fluid supply line to the patient may be unidirectional from the first end to the second end. The connector can be made with the possibility of detachable fluid connection with the outlet socket for draining to supply fluid to the patient.

[0010] According to another embodiment, a method for supplying a fluid using a disposable disposable kit connector may include fluidly connecting a disposable kit disposable fluid inlet jack to a reusable disposable kit (MUDS) connector and establishing fluid communication between the outlet to discharge the connector a disposable disposable kit and an input socket for draining the MUDS kit. The method may further include pumping a disposable replacement kit connector by supplying fluid from the fluid inlet to the outlet for discharging through the fluid line and disconnecting the fluid line from the outlet to the drain. The method may further include supplying fluid from the fluid inlet to the connector along the fluid line. In some embodiments, the method may include attaching the disposable disposable kit connector to the MUDS kit before pumping the disposable disposable kit connector.

[0048] With reference to FIG. 2, the fluid injection system 100 comprises an MUDS 130 kit that is releasably connected to the fluid injection system 100 for supplying one or more fluids from one or more sources 120 of ready-to-drink fluid to a patient. The MUDS 130 may contain one or more syringes or pumps 132. In some embodiments, the number of syringes 132 may correspond to the number of ready-to-use liquid sources 120. For example, in FIG. 2, the MUDS 130 kit contains three syringes 132 located side by side, so that each syringe 132 can establish a fluid connection to one or more sources 120 of ready-to-use fluid. In some embodiments, one or two ready-to-use fluid sources 120 are configured to connect to one or more syringes 132 of the MUDS 130 kit. Each syringe 132 can fluidly connect to one of the ready-to-use fluid sources 120 using a suitable ready-made fluid connector 118 the use of fluid and the associated fluid channel 134 of the MUDS kit. The fluid channel 134 of the MUDS kit may include a needle member that connects to a ready-to-use fluid connector 118. In some embodiments, the ready-to-use fluid connector 118 may be - provided directly on the MUDS 130 kit.

[0049] As also shown in FIG. 2, the MUDS 130 kit may be removably connected to the housing 102 of the fluid injection system 100. It will be apparent to one of ordinary skill in the art that it may be desirable to fabricate at least a portion of the MUDS 130 kit from transparent medical plastic to facilitate visual confirmation of the fact that a fluid connection to the fluid injection system 100 has been established. Visual confirmation is also desirable in order to ensure that there are no air bubbles in the various fluid compounds. Alternatively, at least a portion of the MUDS 130 kit and / or door 116 may include windows (not shown) for visualizing the connection between the various components. Various optical sensors (not shown) may also be provided to detect and confirm the connections. In addition, various lighting elements (not shown) may be provided, such as light emitting diodes (LEDs), to which one or more optical sensors react, and which indicate that a suitable connection has been established between the various components.

[0050] Let us consider in more detail FIG. 2, which shows a schematic illustration of various channels for a liquid of a liquid introduction system 100. The MUDS 130 kit may include one or more valves 136, such as shut-off valves, under which a medical fluid or combination of medical fluids is taken from a multi-dose source 120 of ready-to-use fluid and / or is supplied to a patient through each syringe 132. In some embodiments, one or multiple valves 136 may be provided at the distal end 140 of multiple syringes 132 or at a manifold 148. The manifold 148 may be in fluid communication through valves 136 and / or syringes 132 with a first end om channel 134 for fluid kit MUDS, which connects each syringe 132 with a corresponding source 120 of ready-to-use fluid. The opposite second end of the fluid passage 134 of the MUDS kit is configured to connect to a respective ready-to-use fluid connector 118, which is fluidly coupled to the ready-to-drink fluid source 120. Depending on the position of one or more valves 136, fluid may be drawn into one or more syringes 132, or it may be dispensed from one or more syringes 132. In the first position, for example, during filling of syringes 132, one or more valves 136 are oriented so that the fluid flows from the ready-to-use fluid source 120 to the desired syringe 132 through the fluid inlet line 150, such as the fluid channel of the MUDS kit. During the filling procedure, one or more valves 136 are arranged such that fluid flow through one or more of the fluid outlet lines 152 or manifold 148 is blocked. In the second position, for example, during the fluid supply procedure, fluid from one or more syringes 132 is supplied to the manifold 148 through one or more fluid outlet lines 152 or through the outlet ports of the syringe valve. During the feed procedure, one or more valves 136 are arranged such that fluid flow through one or more fluid inlet lines 150 is blocked. One or more valves 136, fluid inlet lines 150 and / or fluid outlet lines 152 may be placed in a manifold 148. One or more valves 136 may be selectively set to a first or second position by manual or automatic manipulation. For example, an operator may set one or more valves 136 in position to fill or supply fluid. In other embodiments, at least a portion of the fluid injection system 100 allows one or more valves 136 to be automatically positioned to fill or supply fluid based on data entered by an operator, as described herein.

[0051] Continuing with consideration of FIG. 2, in some embodiments, a fluid outlet 152 may also be connected to a drain tank 156 in the fluid injection system 100. Desirably, the drain tank 156 is separated from the syringes 132 to prevent contamination. In some embodiments, the drain tank 156 is configured to receive drain fluid discharged from syringes 132, for example, during a pumping operation. The drain tank 156 may be removable from the housing 102 so that the contents of the drain tank 156 can be disposed of. In other embodiments, the drain tank 156 may have a drain slot (not shown) for draining the contents of the drain tank 156 without removing the drain tank 156 from the housing 102. In some embodiments, the drain tank 156 is provided as a separate component from the MUDS kit 130.

[0052] Having completed the general description of the components of the fluid injection system 100 and the MUDS 130 kit, we proceed to describe the design and method of using the disposable disposable kit 190 (SUDS) and its interaction with the MUDS 130 kit.

[0053] With reference to FIG. 3A and 3B, the fluid injection system 100 comprises a connector socket 192, which is configured to form a fluid connector with at least part of the SUDS 190. In some embodiments, the connector 192 may be formed in the MUDS 130. The connector 192 may be covered by at least a portion of the housing 102 of the fluid injection system 100. For example, placing the connecting socket 192 in a recess in the interior of the housing 102 may maintain the sterility of the connecting socket 192 by preventing or restricting the user or patient from touching portions of the connecting socket 192 that come into contact with the fluid to be injected into the patient and contaminate these parts. In some embodiments, the connection socket 192 is located in a recess within the opening 194 formed in the housing 102 of the fluid injection system 100, or the connection socket 192 may include a closure member (not shown) that surrounds at least a portion of the connection socket 192. In other embodiments the implementation of the connector socket 192 can be formed directly in the housing 102 and connected to the kit MUDS 130 through a channel for liquid (not shown). As described herein, the SUDS 190 can be connected to a connector 192 formed at least in part of the MUDS 130 and / or housing 102. It is desirable that the connection between the SUDS 190 and the connector 192 is a detachable connection to provide selectively disconnecting the SUDS 190 kit from the connecting socket 192 (FIG. 3A) and connecting to the connecting socket 192 (FIG. 3B). In some embodiments, the SUDS 190 kit can be disconnected from the connector 192 and discarded after each fluid delivery procedure, and a new SUDS 190 complex can be connected to the connector 220 for the next fluid delivery procedure.

[0054] Continuing with consideration of FIG. 3A and 3B, separately from the connection socket 192, an inlet socket 196 may be provided. The drain inlet socket 196 is in fluid communication with the drain tank 156. In some embodiments, the drain tank 156 is provided separately from the SUDS 190, so that fluid from the drain inlet 196 can be supplied to the drain tank 156. At least part of the SUDS 190 can be detachably connected to or connected to a drain inlet 196 for draining the drain liquid into the drain tank 156, for example, during a pumping operation in which air is forced out of the SUDS 190. The drain tank 156 may have a viewing window 198 with a scale of 200, such as calibration marks that indicate the fill level of the drain tank 156.

[0055] With reference to FIG. 4A, the SUDS 190 kit has an inlet socket 202 for fluid that is plug-and-socket with a connection socket 192 (shown in FIG. 3A). The liquid inlet 202 accepts liquid supplied from the liquid introduction system 100. Preferably, the fluid inlet 202 is a hollow, tubular member, as shown in FIG. 4B. The SUDS 190 kit further includes a drain outlet 204 that is plug-in or communicable with a drain outlet 196 (shown in FIG. 3A). The outlet drain socket 204 receives the drain liquid and delivers the drain liquid to the drain tank 156, for example, during the pumping operation of the SUDS 190. It is desirable that the drain outlet 204 be a hollow, tubular member, as shown in FIG. 4B. The drain outlet 204 may be connected to, inserted in, or located in the drain inlet 202 so that the drain liquid can flow through the drain inlet 202 and from there to the drain tank 156. The liquid inlet 202 and the drain outlet 204 may be separated by a spacer 206. In some embodiments, the spacer 206 is sized to align the liquid inlet 202 and the drain outlet 204 with a connection socket 192 and an input socket 196 for draining, respectively. Note that the SUDS 190 set is shown in FIG. 4A is in a state after being removed from the package (not shown). Before use, the SUDS 190 kit is preferably packaged in a pre-sterilized, hermetically sealed packaging that protects the SUDS 190 kit from contamination with substances in the air or on surfaces. Alternatively, the hermetically sealed packaging and the SUDS 190 kit can be sterilized after packaging.

[0056] The SUDS 190 kit desirably has an asymmetric design so that the user can only attach the SUDS 190 kit to the MUDS 130 kit in one orientation. Due to this, it is not allowed for the user to attach the fluid inlet socket 202 to the drain inlet socket 196. In some embodiments, a tide 207 may be provided on at least a portion of the SUDS 190 to prevent the SUDS 190 from being improperly inserted into the connector 192. In certain embodiments, the tide 207 may be formed on a splitter 206 adjacent to the drain outlet 204. Thus, tide 207 can prevent the SUDS 190 kit from being inserted incorrectly into the connector 192. To prevent the SUDS 190 kit from being inserted incorrectly into the connector 192, elements and shapes other than tide 207 can be used.

[0057] In some embodiments, a tube system 208 may be coupled at its proximal end 210 to a fluid inlet 202. The tube system 208 is configured to supply fluid received from a fluid inlet 202. The distal end 212 of the tube system 208 may include a connector 214 that is configured to connect to a drain outlet 204 or a fluid channel connected to a patient (not shown). The tube system 208 may be made of resilient material, such as medical plastic, which allows the tube system 208 to be coiled. Connector 214 may be a Luer connector (either a Luer male connector or a Luer female connector, depending on the desired application) or another type of medical connector. In some embodiments, connector 214 may have a check valve to prevent backflow of fluid. Alternatively, a check valve may be located anywhere in the SUDS 190 between the fluid inlet 202 and the connector 214.

[0058] Continuing with consideration of FIG. 4A, the SUDS 190 may have a locking protrusion 216 that is selectively lockable to the SUDS 190 with the fluid injection system 100 depending on engagement of the locking protrusion 216 with at least a portion of the fluid injection system 100. In some embodiments, the locking protrusion 216 may be an elastic protrusion that is configured to deviate from the engaged position to the free position and vice versa by deflecting at least a portion of the locking protrusion 216. The locking protrusion 216 may have a pressing surface 218 that, when pressed, causes the locking to be deflected. the protrusion 216 from the meshing position to the free position for inserting the SUDS 190 into the fluid introduction and removal system 100. In some embodiments, the locking protrusion 216 may be detachably locked with a receiving groove 217 in the MUDS 130 kit (shown in FIG. 4C).

[0059] With reference to FIG. 4B, the SUDS 190 may have a first annular skirt 224 extending around the circumference of the proximal end 226 of the fluid inlet 202 and a second annular skirt 220 extending around the circumference of the distal end 222 of the fluid inlet 202. The first and second annular skirts 224, 220 surround the fluid inlet 202 to prevent accidental contact and contamination. The first annular skirt 224 may have one or more recesses 228 (shown in FIG. 4A) extending along its side wall. One or more recesses 228 may provide a locking boundary with a corresponding locking element (not shown) in the fluid injection system 100. The second annular skirt 220 may have at least one recess 230 (shown in FIG. 4A) to facilitate grip and handling of the SUDS 190. In some embodiments, the second annular skirt 220 may have a raised surface having one or more ribs 232 (shown Fig. 9A) to facilitate grip and handling of the SUDS 190 kit.

[0060] Continuing with consideration of FIG. 4B, at least one o-ring 234 may be provided around the proximal end 226 of the fluid inlet 202. At least one O-ring 234 may seal the fluid inlet 202 to prevent fluid from flowing through the SUDS 190. At least one O-ring 234 may provide a fluid seal between the SUDS 190 and the MUDS 130 when they are in fluid communication. on the other hand, making fluid movement possible from the MUDS 130 kit to the SUDS 190 kit without leakage. A check valve 236 may be provided within the cavity of the fluid inlet 202 to prevent fluid from traveling in the opposite direction from the SUDS 190 kit to the MUDS 130 kit.

[0061] With reference to FIG. 4C, the SUDS kit 190 shown in FIG. 4A, is shown connected to a fluid injection system 100. Although in FIG. 4C shows a connection socket 192 formed in the MUDS 130, in other embodiments, a connection socket 192 may be formed in a part of the housing 102 (shown in FIG. 1). The fluid inlet socket 202 of the SUDS 190 is connected to the connection socket 192 to create a fluid channel in the direction of arrow F shown in FIG. 4C. Fluid passing through the fluid inlet 202 flows through a check valve 236 and into a tube system 208. All liquid that can drip from the boundary between the liquid inlet 202 and the connecting socket 192 is collected in the drain tank 156. The drain tank 156 may take the form of collecting all the liquid that may drip from the SUDS 190 when it is removed from the MUDS 130. In addition, when the SUDS 190 is connected to the connection socket 192, the outlet of the drain outlet 204 is located in within the inlet drain port 196 so that the drain fluid from the tube system 208 can be discharged into the drain tank 156. The spacer 206 may define a restrictive insertion surface defining the depth of insertion of the SUDS 190 into the connector 192.

[0062] With reference to FIG. 5A, the fluid injection system 100 may include a sensor system 238 that is recognizable when the SUDS 190 is in fluid communication with the MUDS 130. The sensor system 238 may include at least one sensing element, for example, a sensor flood 240 the SUDS 190 kit and the corresponding sensor 242 in the fluid injection system 100 or the MUDS 130 kit. The sensor 242 can be configured to detect the presence and absence of at least one tide 240 of a sensor or other sensitive element. In some embodiments, a sensing element, such as at least one sensor spike 240, is formed on the locking protrusion 216 of the SUDS 190, as shown in FIG. 4A. In other embodiments, a sensing element, for example, at least one sensor spike 240, may be formed on any part of the SUDS 190. The sensor 242 may be an optical sensor located and fixed within a respective frame formed on the housing 102 of the fluid injection system 100 . As will be appreciated by those skilled in the art of mechanized medical fluid injectors, the sensor 242 may be electronically coupled to an electronic control device used to discretely control the operation of the fluid injection system, for example, the operation of one or more piston elements, at least in part from the sensor input 242. A sensing element, such as a sensor tide 240, may have one or more reflective surfaces that reflect visible or infrared light, which must recognize sensor 242. In other embodiments, there may be used mechanical interaction between the sensor element and the sensor 242.

[0063] In some embodiments, the SUDS 190 kit may further comprise reusable elements (not shown). For example, the SUDS 190 kit may contain one or more fragile sensor elements, protrusions, or structures that bend or break when the SUDS 190 kit is removed from the MUDS 130 kit. The absence of these elements may prevent the SUDS 190 kit from being reinserted and used after removal. In this way, it can be ensured that the SUDS 190 kit will be used for only one fluid supply procedure.

[0064] Having completed the general description of the components of the fluid injection system 100, the MUDS 130 kit, and the SUDS 190 kit, we proceed to a detailed description of the method of using the SUDS 190 kit. During use, the healthcare provider or user removes the replacement SUDS 190 from its packaging (not shown) and inserts fluid inlet 202 to connector 192 on the MUDS 130 kit. As described above, the SUDS 190 must be inserted in the correct orientation so that the fluid inlet 202 is aligned to connect to the connector nym jack 192, and output port 204 to drain was aligned to connect with an input socket 196 for draining. The SUDS 190 kit can be attached to the MUDS 130 kit by inserting the locking protrusion 216 into the receiving groove 217 on the MUDS 130 kit. When the SUDS 190 kit is firmly connected to the MUDS 130 kit, for example, when the sensor 242 indicates this, the fluid injection system 100 ( shown in Fig. 1) draws fluid into one or more of the number of syringes 132 of the MUDS 130 kit and performs an automatic pumping operation to remove air from the MUDS 130 kit and SUDS 190 kit. During such a pumping operation, fluid from the MUDS 130 kit is introduced through the connector Noe socket 192 and tubing 208 in the kit SUDS 190. The fluid passes through tubing 208 and through the output port 204 to drain and into the reservoir 156 to drain. When the automatic pumping operation is completed, the medical professional disconnects the connector 214 from the outlet 204 for draining. After this, connector 214 can be connected to the patient via a catheter, vascular access device, needle, or optional fluid channel kit to facilitate fluid delivery to the patient. When the fluid supply is complete, the SUDS 190 kit is disconnected from the patient and the MUDS 130 kit by disengaging the locking tab 216 of the SUDS 190 from the engagement groove 217 on the MUDS 130 kit. After that, the healthcare provider may discard the SUDS 190 kit. In certain embodiments, removing the kit The SUDS 190 from the MUDS 130 kit activates reusable items (not shown), thereby eliminating the re-insertion and use of the SUDS 190 kit.

[0065] With reference to FIG. 6, the interface between the SUDS 190 and the MUDS 130 is shown in accordance with another embodiment. The MUDS 130 kit has a connecting socket 192, which can be made in the form of a hollow tubular element with a Luer connector 24 (either a Luer plug connector or a Luer female connector, depending on the desired application), which extends from the distal end of the socket 192 into the socket 192. Accordingly, the proximal opening of the Luer connector 24 is located in a recess within the interior of the socket 192. The Luer connector 24 may comprise a screw thread 30 (shown in FIG. 7B) for attaching the MUDS 130 kit to the computer to SUDS 190. For example, a screw thread 30 may be located on the outer casing 32 surrounding the Luer connector 24, as shown in FIG. 7A and 7B. Screw thread 30 may also be located on the Luer connector 24 itself. The Luer connector 24 defines a fluid passage 34 (shown in FIG. 7B) that passes through it, from the proximal end of the connection socket 192 to its distal opening. Although connector 192 is depicted as including a Luer connector 24, other types of connectors may be used within the scope of the present invention, including but not limited to clamp connectors, bayonet connectors, tight fit connectors, and the like. In addition, in certain embodiments the implementation of the connector 24 for the connector socket 192 is desirably a non-standard connector (e.g., an unusual size or shape connector) to prevent attachment of connectors that are made pouring third parties.

[0066] The MUDS 130 kit has an inlet socket 196 for draining (shown in Fig. 6), which can also be made in the form of a hollow tubular element. The drain inlet socket 196 comprises a cone-shaped distal nozzle 36 attached to a fluid conduit, such as a resilient tubing system 208 made of medical polymer, which connects the drain inlet socket 196 to a drain reservoir 156 (shown in FIG. 2).

[0067] Returning to FIG. 6, as described in detail herein, the MUDS 130 is configured to connect to the SUDS 190, which is discarded after first use. Note that the SUDS 190 set is shown in FIG. 6 in a state after removal from packaging (not shown). Before use, the SUDS 190 kit is preferably packaged in a pre-sterilized, hermetically sealed packaging that protects the SUDS 190 kit from contamination with substances in the air or on surfaces.

[0068] The SUDS 190 kit may include two or more sockets corresponding to the connecting socket 192 and the input socket 196 for draining the MUDS 130. For convenience, the sockets of the SUDS 190 are equivalent to the liquid input socket 202 and the output socket 204 for draining the SUDS 190, described with reference to FIG. 4A-4B. Slots 202, 204 may be provided in a protective sheath 42, which may be received by the housing 20 of the MUDS 130 kit, as shown in FIG. 7B. The containment shell 42 is desirably asymmetric so that the user can only attach the SUDS 190 kit to the MUDS 130 kit in one orientation. So, for example, the user cannot attach the connecting socket 192 of the MUDS 130 kit to the output socket 204 for draining the SUDS 190 kit. The sockets 202, 204 and the protective sheath 42 of the SUDS 190 kit can be made of a material suitable for medical use, such like medical plastic. The SUDS 190 tubing system 208 is connected between the proximal end of the fluid inlet 202 and the end of the drain outlet 204 through shut-off valves. Tube system 208 may be provided as a coil or coil for ease of packaging and maneuverability.

[0069] With reference to FIG. 7A and 7B, the fluid inlet socket 202 of the SUDS 190 kit is a hollow, tubular member adapted to be inserted into the coupling socket 192 of the MUDS 130 kit. The fluid inlet 202 of the SUDS 190 kit includes a tubular groove, such as a Luer connector 44, forming a fluid passage 46 that extends from the proximal end of the socket 202 adjacent to the MUDS 130 and the distal end of the socket 204 connected to the tube system 208. The Luer connector 44 is configured to connect to the Luer connector 24 of the MUDS 130 kit. When firmly connected, the connector 192 of the MUDS 130 kit is in fluid communication with the fluid inlet 202 of the SUDS 190 kit. The Luer connector 44 may include a wheel 52 for attaching the connector 192 of the MUDS 130 kit to the fluid inlet 202 of the SUDS 190 kit. The wheel 52 may be formed integrally with the Luer connector 44 or may be a separate element rigidly connected to the 44 L connector era conventional means. The wheel 52 rotates the Luer connector 44, as a result of which the protrusions 54 which extend away from it engage with a corresponding screw thread 30 in the connecting socket 192. The tube system 208 is connected to the liquid inlet 202 through an opening 56 on the wheel 52, so that a continuous fluid connection is established between the MUDS 130 kit and the 208 tubing system.

[0070] Continuing with consideration of FIG. 7A and 7B, the SUDS 190 also includes an outlet socket 204 for draining the SUDS 190. The outlet 204 for draining the SUDS has a fluid passage 58 formed by a tubular groove 60 between the drain socket 196 of the MUDS 130 and the system 208 tubes. The tube system 208 may not be connected directly to the input socket 196 for draining the MUDS 130 kit. Instead, the tubing groove 60 of the SUDS 190 kit can separate the pipe system 208 from the MUDS 130, thereby isolating the pipe system 208 and connector 214 from the input jack 196 for draining the MUDS 130 kit. The tubular groove 60 may be located in a recess relative to the inlet socket 196 for draining the MUDS 130 kit through a portion of the protective sheath 42 of the disposable connector to reduce the likelihood of contamination. The tubular groove 60 may also be angled horizontally to facilitate fluid flow through the outlet 204 for draining the SUDS 190 and entering the draining inlet 196 of the MUDS 130. In some embodiments, the SUDS 190 may further comprise elements that do not reusable (not shown). For example, the SUDS 190 kit may contain brittle protrusions or structures that bend or break when the SUDS 190 kit is removed from the MUDS 130 kit. In this way, it can be ensured that the SUDS 190 kit will be used for only one fluid delivery procedure.

[0071] With reference to FIG. 8A-8F, a method of operating an embodiment of a connection node between SUDS 190 and MUDS 130 sets shown in FIG. 6-7V. During use, the healthcare professional or user removes the interchangeable SUDS 190 from its packaging and inserts the SUDS 190 kit into the appropriate MUDS 130 kit. As described above, the SUDS 190 kit must be inserted in the correct orientation so that the connector socket 192 of the MUDS 130 kit fits into the engagement with the fluid inlet socket 202 of the SUDS 190 kit, and the inlet socket 196 for draining the MUDS 130 kit is engaged with the outlet jack 204 for draining the SUDS 190 kit. As shown in FIG. 8B, then the healthcare professional turns the wheel 52 to attach the SUDS 190 to the MUDS 130. When the SUDS 190 is firmly connected to the MUDS 130, the fluid injection system 100 (shown in FIG. 1) draws fluid into one or more of a number of syringes 132 of the MUDS 130 kit and performs an automatic pumping operation (Fig. 8C) to remove air from the MUDS 130 kit and the SUDS 190 kit. During such a pumping operation, fluid from the MUDS 130 kit is introduced through the connecting socket 192 and into the tube system 208 of the SUDS kit 190. Liquid rohodit through a system of tubes 208 and 204 through the output jack to drain and into the reservoir 156 to drain. When the automatic pumping operation is completed, the medical professional disconnects the connector 214 from the outlet 204 for discharge (Fig. 8D). After this, connector 214 can be connected to the patient via a catheter, vascular access device, needle, or optional fluid channel kit to facilitate fluid delivery to the patient (FIG. 8E). When the fluid supply is complete, the user disconnects the connector 214 by rotating the wheel 52 to remove the SUDS 190 from the MUDS 130 (FIG. 8F). Thereafter, the healthcare professional may discard the SUDS 190 kit. In certain embodiments, removing the SUDS 190 kit from the MUDS 130 kit results in reusable items (not shown), such as protrusions that extend from part of the SUDS 190 kit, bend or break, except for reinserting the SUDS 190 kit.

[0072] With reference to FIG. 9, another embodiment of a connector assembly having an SUDS 190 kit and a MUDS 130 kit is shown. In this embodiment, the assembly of an SUDS 190 kit includes a cannula receptacle 62 for receiving a needle cannula 129 connected to a connector 214. A cannula 129 used to deliver fluid to a patient can be inserted into the cannula seat 62 after being removed from the patient. The cannula nest 62 may cover the contaminated end of the cannula 129 when the cannula 129 is discarded. In this embodiment, the disposable protective sheath 42 is desirably long enough so that the entire length of the needle cannula 129 can be inserted into the protective sheath 42 for safe disposal.

[0073] With reference to FIG. 10A and 10B, another embodiment of a connector assembly having an SUDS 190 kit and a MUDS 130 kit is shown. The connector assembly is provided in a vertical orientation, with a connector socket 192 of the MUDS 130 kit located above the drain inlet socket 196. The MUDS 130 kit includes a drip channel 64 that extends between the connecting socket 192 and the drain inlet 196. All the fluid that flows from the connector 192 is directed down the drip channel 64 due to gravity. The drip channel 64 opens into the inlet socket 196 for discharge. Accordingly, all liquid leaving the drip channel 64 is guided through the drain outlet 196 and is collected in the drain tank 156. Alternatively, an absorbent material, such as absorbent wipe 66 shown in FIG. 10C surrounding a portion of the connecting socket 192 and the drain outlet 196. The absorbent material is designed to absorb all of the liquid that may drip during removal of the SUDS 190 kit in order to more effectively deal with leakage.

[0074] With reference to FIG. 11A-11C, another embodiment of a connector assembly having an SUDS 190 kit and an MUDS 130 kit with multiple tight-fitting connectors is shown. As shown in FIG. 11A, the SUDS 190 kit includes an inlet 202 for a liquid and an outlet 204 for a drain. Instead of a wheel, the SUDS 190 kit includes detachable protrusions 68. The SUDS 190 kit also contains an alignment element 70 that extends from the containment shell 42 of the SUDS 190 and is configured to be inserted into the corresponding groove 72 of the MUDS 130 kit (shown in Fig. 11B).

[0075] As shown in the cross-sectional view shown in FIG. 11C, the SUDS 190 kit is inserted into and aligned with the MUDS 130 kit through alignment grooves 71. The detachment protrusions 68 are formed integrally with a tubular casing 74 having an inwardly facing flange 76. The casing 74 surrounds the tubular groove 80 on the SUDS 190. When the SUDS 190 is inserted in the MUDS 130, the flange 76 is interference fit with the corresponding flange 78 extending from the portion of the coupling socket 192 of the MUDS 130 kit. The interference fit creates a substantially fluid tight connection between the MUDS 130 kit and the SUDS 190 kit. Pressing the tabs 68 to disconnect the SUDS 190 kit flanges flange 76 captive with crest 78 allowing the user to remove the set 190 from the kit SUDS MUDS 130. Referring to FIG. 12, a connection node having a MUDS 130 kit and an SUDS 190 kit with the detachment protrusions 68 described above can also be provided in a vertical configuration.

[0076] With reference to FIG. 13A and 13B, yet another embodiment of a connector assembly having an SUDS 190 kit and an MUDS 130 kit is shown. The MUDS 130 kit includes a connecting jack 192 and a drain inlet 196, as described in previous embodiments. Connector socket 192 includes a co-molded sealing surface 82 to provide a seal between the SUDS 190 kit and the MUDS 130 kit. The SUDS 190 kit includes external alignment surfaces 84 formed integrally with the sheath 42 to properly align the SUDS 190 kit and the MUDS 130 kit. Surfaces 84 alignments are also recessed with respect to the fluid inlet 202 and the draining outlet 204 of the SUDS 190 to reduce the chance of contamination before use.

[0077] With reference to FIG. 14A-16B, various embodiments of a tube system 208 are shown. For example, the tube system 208 can be wound around a support member 133, such as a core or frame part, to ensure that the tube system 208 does not unwind when it is removed from the package or when the SUDS 190 kit is connected to the MUDS 130 kit. with reference to FIG. 16A, the tube system 208 may further comprise a removable outer clip 135. The clip 135 is closed around a coiled tube system 208 so that the tube system 208 does not unwind during removal from the package or auto-bleed. With reference to FIG. 16B, in a further embodiment, deployed portions 137 are provided in the tube system 208 to shield the tube system 208 from the SUDS 190. The folded portion 139 of the tube system 208 hangs below the deployed portions 137 when the SUDS 190 is connected to the MUDS 130.

[0078] With reference to FIG. 17, an electronic control device 900 (shown in FIG. 17) may be coupled to a fluid injection system 100 to control filling and supply operations. In some embodiments, the electronic control device 900 may control the operation of various valves, piston elements, and other elements to influence the necessary filling or feeding procedure. For example, the electronic control device 900 may comprise a number of discrete computer-readable media. For example, these computer-readable media can contain any media that can be accessed by the electronic control device 900, for example: volatile media, non-volatile media, removable media, non-removable media, intermediate media, non-removable media, etc. As a further example, these computer-readable media may comprise computer storage devices, such as media implemented by any method or technology, for storing information such as computer-readable instructions, data structures, program modules or other data; random access memory (RAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), flash memory or other storage technologies; compact discs, digital versatile disks (DVDs), or other optical disk storage devices; magnetic tape cassettes, magnetic tapes, magnetic disk storage devices or other magnetic storage devices; or any other media that can be used to store the necessary information, and which can be accessed by the electronic control device 900. Additionally, these computer-readable media may include communication media such as computer-readable instructions, data structures, program modules or other modulated data an information signal, such as an electromagnetic signal for transmitting modulated information, or another transfer mechanism, and include all information delivery vehicles wired with COROLLARY (such as wired networks and direct-wired connection) or wireless means (such as audio signals, RF signals, optical signals, infrared signals, biometric signals bar-code signals, etc.). Of course, combinations of any of the above objects should also be included within the scope of computer-readable media.

[0079] The electronic control device 900 further comprises a system memory 908 with computer drives in the form of volatile and non-volatile memory, such as ROM and RAM. The basic input / output system (BIOS), with the appropriate computer standard routines, helps to transfer information between components within the electronic control device 900 and is usually stored in ROM. The random access memory of the system memory 908 typically contains data and program modules that can be directly accessed or currently processed by the processing module 904, for example, the operating system, application program interfaces, application programs, program modules, program data and other command machine-readable codes.

[0080] Continuing with consideration of FIG. 17, the electronic control device 900 may also include other removable or non-removable, volatile or non-volatile, intermediate or non-intermediate computer storage products. For example, the electronic control device 900 may comprise a non-removable memory interface 910 that communicates with and controls a hard disk 912, for example, a non-removable, non-volatile magnetic storage device; and a removable non-volatile memory interface 914 that communicates with and controls a magnetic drive 916 (which reads from and writes to a removable, non-volatile magnetic disk 918), an optical drive 920 (which reads from and writes to a removable, non-volatile optical disk 922, such as CD), port 921 of the universal serial bus (USB) for use when connecting to a removable memory card, etc. However, it is contemplated that other removable or non-removable, volatile, or non-volatile computer storage devices may be used in the illustrative computer complex 902, including but not limited to magnetic tape tapes, DVDs, digital video tapes, solid state RAM, solid state ROMs, etc. .d. These various removable or non-removable, volatile or non-volatile magnetic media communicate with the processing module 904 and other components of the electronic control device 900 via a system bus 906. The drives and associated computer drives discussed above and shown in FIG. 17 provide storage of operating systems, computer-readable instructions, application programs, data structures, program modules, program data and other computer-readable command codes for electronic control device 900 (regardless of whether or not they duplicate this information and data in system memory 908) .

[0081] The user can enter commands, information and data into the electronic control device 900 through certain plug-in or ready-to-use input devices, such as the user interface 124 shown in FIG. 1A using the user input interface 928. Of course, many such input devices can be used, for example, a microphone, trackball, joystick, touch panel, touch screen, scanner, etc., including any device that facilitates inputting data and information to the electronic control device 900 from an external source. As already discussed, these and other input devices are often connected to the processing module 904 via a user input interface 928 connected to the system bus 906, but can be connected using other interface elements and a bus, such as a parallel input / output port, game port or USB. In addition, data and information can be presented or presented to the user in an understandable form or format by means of certain output devices, such as a monitor 930 (to visually display this information and data in electronic form), a printer 932 (to physically display this information and data in printed form), column 934 (for acoustic presentation of this information and data in acoustic form), etc. All of these devices communicate with the electronic control device 900 via an output interface 936 connected to the system bus 906. It is contemplated that any such peripheral output devices may be used to provide the user with information and data.

[0082] The electronic control device 900 can operate in a network environment 938 by using a communication device 940 that is integrated into or away from the electronic control device 900. This communication device 940 operates under control and in conjunction with the remaining components of the electronic control device 900 due to the communication interface 942. With this arrangement, the electronic control device 900 may be connected to or otherwise exchange information with one or more remote computers, such as a remote computer 944, which may be a personal computer, server, router, network personal computer, peer-to-peer device, or other conventional network nodes, and, as a rule, contains many or all of the components described above in connection with the electronic control device 900. Using suitable communication devices 940, for example, a modem, a network interface nce or adapter, etc., computer 944 can work in and exchange information through a local area network (LAN) and a wide area network (WAN), but can also contain other networks, such as a virtual private network (VPN), an office network , local network of the enterprise, internal network, Internet, etc.

[0083] In the context of this application, the electronic control device 900 comprises or is capable of executing appropriate custom-made or standard software to carry out and implement the processing steps of the method and system of the present invention, thereby forming a specialized and special computing system. Accordingly, the inventive method and system may include one or more electronic control devices 900 or similar computing devices, including a computer-readable drive capable of storing computer-readable program code or instructions, the execution of which, the processing module 904 executes, regulates or otherwise implements methods, processes and manipulations data conversion, which are discussed hereinafter in connection with the present invention.

[0084] One skilled in the art will understand that a system may use databases physically located on one or more computers, which may or may not be similar to their respective servers. For example, software on an electronic control device 900 may manage a database physically located on a separate network processor or other medium.

[0085] In some embodiments, the electronic control device 900 may be programmed so that automatic refilling occurs based on a predetermined trigger minimum volume in respective syringes 132. For example, when the volume of liquid remaining in at least one of the syringes 132 becomes below a predetermined volume, the electronic control device 900 automatically starts the syringe refill procedure. An electronic control device 900 associated with the fluid injection system 100 may determine that a predetermined trigger minimum volume has been achieved by monitoring the volume of fluid supplied from the respective syringes 132 during operation of the fluid injection system 100. Alternatively, liquid level sensors may be integrated in the liquid injection system 100, and input from these liquid level sensors may be provided to the electronic control device 900 so that the electronic control device 900 can determine when a predetermined target has been reached in at least one of the syringes 132 starting minimum volume. The filling volume and refilling rate can be set in the electronic control device 900. The automatic refilling procedure can either be stopped automatically by the electronic control device 900 or interrupted manually. In addition, an automatic refill procedure can be started when, at the end of the liquid injection procedure, at least one of the syringes 132 does not have enough liquid left to perform the next predetermined liquid injection procedure.

[0086] It is possible that during the refill procedure, one or more ready-to-use fluid sources 120 associated with respective syringes 132 may remain empty (eg, initially there is not enough fluid to complete the full refilling of one or more syringes 132). In such a case, it is necessary to replace the source 120 of ready-to-use liquid, and it is desirable that the replacement of such a source 120 of ready-to-use liquid be completed quickly. The fluid injection system 100 may include an indicator, such as an audible and / or visual indicator, to alert the operator to replace the source 120 of ready-to-drink fluid 120 before the fluid injection system 100 can be used.
